Editing Leviathan (section)

====Underground Water Manipulation====
If the target location has intact underground water infrastructure (e.g., sewers, water supply network), instead of calling a tidal wave,<ref name="8.5 eRetaliate" /> he can use this time to manipulate the water in pressurized pipes with the goal of destroying this infrastructure. After bringing these pipes to the surface and cracking open the ground,<ref>The roads beneath us were damaged, shattered.  When Leviathan had shifted the position of the storm sewers, he’d gone all out, and he’d gone a step further than just the storm sewer – he’d also torn up the water supply network for the city.  The occasional pipe speared up between the slats in the sidewalk, fire hydrants were dislodged, and the water that poured from these was barely a trickle now.  That might have meant too much was leaking from the damaged pipes to give the water any pressure. - [https://parahumans.wordpress.com/2012/03/17/extermination-8-5/ Excerpt] from [[Extermination 8.5]]</ref><ref>Water sprayed in the truck’s wake as we cut a path through the flooded streets.<br><br>It was a military vehicle.  I wasn’t one to know much about cars, and I knew even less about stuff like military vehicles, so I couldn’t put a name to the truck that was carting me and eight of Coil’s workers through the Docks.  It was like a sturdy pickup truck, but the rear section was wider and it was hidden beneath a green tarp that had been stretched over a framework of metal bars.  The tires were massive, with deep treads allowing the truck to navigate all but the most cracked sections of road where Leviathan had brought the underground pipes and drains through the surface. - [[Infestation 11.2]]</ref> Leviathan can then leverage these damaged pipes to temporarily shoot geysers of water at his targets.<ref>Leviathan hopped backwards to create some distance, staggered a little as the more injured of his two legs failed to take his weight, used his smaller hand to stop from falling a second time, poising himself on three limbs.<br><br>Armsmaster used his grappling hook to haul himself close, readying to make another slash for the neck.  He changed his mind as the ground rumbled, pulled the hook free to latch it on a garage door.  Countering his forward momentum, he swung himself to one side of the road, staying out of Leviathan’s reach.<br><br>The ground rumbled again, brief, intense, stopped.<br><br>Armsmaster touched a hand to the side of his visor, and I thought I saw his lips crease in a frown before he turned his head away from me.<br><br>Another fierce rumble, and a crack appeared like a seam down the center of the street, a straight line as far as I could see in either direction.<br><br>Leviathan raised his claw, and the road suddenly split, heaving upward as a concrete pipe wide enough to fit a man crested from the pavement like a whale rising from the waves.  A second later, water gushed forth, veering toward Armsmaster.<br><br>''The storm sewers''. - [[Extermination 8.4]]</ref><ref>*  Geyser - The water running underground is manipulated.  The ground cracks, the water level temporarily drops one step if necessary.  Ground becomes difficult and anyone pushed or pulled at ground level has a chance to be dragged or thrown into hazardous terrain.  Geysers shoot temporarily into the air, which may catch fliers or target defensive fortifications.  Further 'Ground' effects may, for the duration, affect 1-3 individuals in the air, as well.  Water level regenerates to where it was prior to the ground cracking after ~3 rounds. - Comment by Wildbow on Parahumans Discord</ref>
<!-- The true strength of this ability is to create extreme amounts of water pressure and movement in unseen places such as underground aquifers or coastlines. -->

He can demonstrate the true strength of underground water manipulation when the target location has a large aquifer and/or coastal erosion vulnerability. When Leviathan approached [[Brockton Bay]], [[Legend]] informed capes that Brockton Bay was a vulnerable soft target where they could not afford to buy time and let Leviathan build up the strength of his attacks<ref name="8.2 e10" /> because the city was above an aquifer.<ref name="8.2 e11">The television screen showed a cross section of Brockton Bay as seen from ground level.  The West end of the city was bordered by hills, and the terrain sloped gradually from the base of the mountain down to the water.  Directly below the image of the buildings that marked the city’s location, there was a large cavern, bordered by rock on all sides except the part nearest the beach, which was sand.  It was marked blue – filled with water.<br><br>“Brockton Bay, ''this location'', is a soft target.  The city was originally founded at this location because of the proximity to the coastline for trade routes and an aquifier that provided the first settlers with access to fresh water.  This aquifier, essentially an underground lake beneath the city, is our weak point. - [https://parahumans.wordpress.com/2012/03/06/extermination-8-2/ Excerpt] from [[Extermination 8.2]]</ref> He could manipulate this aquifer in an attempt to erode the surrounding sand, silt, and rock, having the end goal of collapsing a section or perhaps most of the city.<ref name="8.2 e12">From the moment Leviathan shows himself, we expect Leviathan will stir and manipulate this underground reservoir to erode the surrounding sand, silt and rock.  Add the tidal waves from above, with the resulting tremors and impacts…”<br><br>I doubted anyone failed to understand what would follow.  A section of the city, perhaps most of the city, could collapse into the aquifier. - [https://parahumans.wordpress.com/2012/03/06/extermination-8-2/ Excerpt] from [[Extermination 8.2]]</ref> After an hour,<ref name="8.5 eHour">More than anything else, though, the two of them had the look of people who had seen half their immediate family brutally and senselessly torn apart over the course of one terrible hour.  As though they’d had their hearts torn out of their chests and were somehow still standing.  It wasn’t that I had seen anyone in those circumstances before, but that look existed, and they had it. - [https://parahumans.wordpress.com/2012/03/17/extermination-8-5/ Excerpt] from [[Extermination 8.5]]</ref> a heavy slam from Leviathan could now collapse a section of [[Downtown]] to form a massive sinkhole<ref>That top-heavy body of his toppled forward, and it was only his right claw, slamming down to the pavement, that stopped his face from being driven into the ground.  The impact of his claw striking the ground rumbled past us.<br><br>The rumble didn’t stop.<br><br>“Run!” I shouted, my cry joining the shouts of others.  I turned, sloshed through the water to get away, not sure where to get away ''from'', or ''to''.<br><br>Leviathan and the ground beneath him sank a good ten feet, and water swirled and frothed as it began pouring to fill the depression.  He used his arm to shield himself as Purity fired another blast from above.  As the ground beneath him continued to sink, the water lapped higher and higher around him.<br><br>The Endbringer descended, and the area around him quickly became a massive indent, ten, fifteen, thirty, then sixty feet across, ever growing.  The force of the water pouring into the crater began to increase, and the ground underfoot grew increasingly unsteady as cracks spread across it.<br><br>I realized with a sudden panic, that I wasn’t making headway against the waves and the ground that was giving way underfoot.  The growing crater was continuing to spread well past me, rising above me as the ground I stood on descended.<br><br>“Need help!” I screamed, as water began falling atop me from a higher point, spraying into me with enough force that I began to stumble back, fall.<br><br>The ground in front of and above me folded into a massive fissure.  The movement of the cracked sections of road created a torrent of water that washed over me, engulfed me and forced me under. - [https://parahumans.wordpress.com/2012/03/17/extermination-8-5/ Excerpt] from [[Extermination 8.5]]</ref> that would later be called a [[Crater Lake|'lake']].<ref name="8.5 e1" /><ref>Our boats weren’t out on the ocean.  We traveled through the area downtown where Leviathan had collapsed a section of the city.  It was now more or less an artificial lake.  The water was fairly still, lapping gently against the ruined roads and collapsed buildings that surrounded the crater, but with the speed these boats were capable of going, even waves a half-foot high made us ramp slightly off one and then crash down onto the next with a sudden spray. - [[Plague 12.2]]</ref> If not stopped over the course of many hours,<ref name="SB sink">'''moridinamael:''' If he just sucked all the water out of rock in the subsurface below Newfoundland, the island would sink. The briney water that permeates all earthly rocks below sea level always helps support some of the overburden pressure of the rock above it. If you suck some of the water out of an aquifer or an oil field, the ground above it will sink. Only a few meters at most, in the worst known scenarios, but Leviathan can move a lot more water than humans with a few wells with limited operating conditions.<br><br>'''Wildbow:''' Yeah. My mental picture of the scene & understanding of how things could theoretically work was that Newfoundland has historically been prone to erosion, and there's a lot of stuff going on with plates and separation from the crust/mantle. Water within the rocks creates a kind of erosion from within, concentrated, high-pressure movement of water erodes the layers most prone to damage while scooping out water while creating a kind of power-augmented hydroplane/sediment layer, and... over the course of hours, it slides beneath.<br><br>Of course, the entire thing goes hand in hand with calamity, waves taller than many boats, people trying to use powers to mitigate the damage and give people a better chance to evacuate, yadda yadda. - Conversation with Wildbow on Reddit, archived on Spacebattles</ref><!-- https://forums.spacebattles.com/posts/39590539 --> Leviathan can eventually even sink or level entire islands as he demonstrated with the complete disappearance of [[Canada|Newfoundland]]<ref name="8.2 e8" /> and the shattered, half-sunken [[Kyushu]].<ref name="26.x e1">There was no guarantee they wouldn’t use Dodge’s technology to visit the United Kingdom or Africa or even shattered, half-sunken Kyushu. - [https://parahumans.wordpress.com/2013/07/25/interlude-26-bonus-1/ Excerpt] from [[Interlude 26.x]]</ref>
